Effectiveness testing of different organic fertilizers on crop yields under climatic conditions of arges county

Application of organic fertilizers has proven a lot of benefits which converge to better yield parameters and food of high quality. The objectives of our study were to research the efficiency of three fertilizers accepted for organic agriculture (CODAMIX -F1, ECOAMINOALGA -F2 and ECOAMINOALGA PLUS -F3) on four different field crops, to evaluate their effects on yield parameters and to compare the results with those obtained in a previous experimental year. The study was developed in Albota, Arges County during 2020-2021 and the field crops subjected to this investigation were winter wheat (Trivale variety), sunflower (PG4 hybrid), maize (T.332 hybrid), soybean (Raluca TD variety). The experimental scheme was composed from four plots and four variants (control, F1, F2, F3) for each crop. Organic fertilizers (F1, F2, F3) were applied for all field crops as two foliar treatments during vegetation period. The obtained results evidenced that application of organic fertilizers increased yield parameters and the efficiency of treatments is following the order F3>F2>F1. The results obtained during 2020-2021 are in good agreement with those reported for 2019-2020.
